Startup Idea : personal black box

We have smart phones that can record everything, but when emergency situation happens, we most often don't have time to react and hit the record button. In cases of mobbing, blackmailing or if you need an emergency response it would even be dangerous. So in the end we don't record anything. My idea is an application that would work like airplane's black box. Always record the last hour or how the user permits the use of memory. If we want to have a longer history of recording can lease Claude services. In the settings can be options like: record only sound, picture and sound, motions, speed,…etc Of course, the application must be on in order to work and it has to be able to activate itself automatically if you leave a certain position or come to a certain position , or if it exceeds a set speed of movement , etc . It would all be listed in settings manual. It could storage everything on Internet, like Cloud system. So if anything happens to you that would make you lose your smart phone, you could look it up in Internet account afterwards.
